Abstract (en)
The superdensity assembly method and system for coiled tubing bundle plastic heat exchangers resists the large buoyancy forces occurring due to ice build-up on the multiple tubes and provides fast melt down in phase change thermal storage tanks. The coiled tubing bundle heat exchanger (10) in the tank is assembled from numerous vertical slippery plastic strips (12) for example, high density polyethylene or ultra high molecular weight polypropylene, having keyhole-shaped slots (14) of predetermined uniform spacing extending inwardly from the front edge of each strip. Each slot terminates in a rounded seat opening (18) spaced inwardly a predetermined distance from the rear edge of the strip. These rounded seat openings have a diameter slightly smaller than the outside diameter of the individual tubes which are made of similar slippery plastic.
